TERNARY CATALYST OF PT-RU-MEOX (ME = MO, W, V) ON CARBON WITH HIGH CO TOLERANCE IN FUEL CELL ANODES AND PREPARATION METHOD THEREOF

摘要

The invention tackles the problem associated with deactivating the anode catalysts of fuel cells. The invention relates to a ternary catalyst of Pt-Ru-MeOX (wherein Me = Mo, W or V) on a carbon support, capable of oxidising CO to CO2 at potentials above 0.1 V in respect of the normal potential of hydrogen (NHE). The invention also relates to the method for preparing said catalysts, as well as the use thereof as anodes in polymer electrolyte or proton exchange membrane fuel cells supplied with hydrogen obtained from reforming (PEMFC) or direct methanol (DMFC).
